scot,
i’m thinking you got too much time on your list. but fwiw, let’s put mark grace on that list. they were far in between but they were glorious dingers.

Babe Ruth? I’m always amused when we attack the recent ages as though they are steroid tainted but past decades were not.
I read about one of these speculative steroid abusing guys who showed up to spring training much larger than the previous season, so much that it caused the local paper to write an article on his increased size. The team was amazed by his upgraded power hitting, but dismayed by his fits of rage, and random crying in the locker room. As the season progressed he even began loosing hair and having strange appetite changes. After this season he slimmed down and never performed at that level again…but his life was somewhat back to normal otherwise. Of course, despite all this, nobody ever accused Roger Maris of steroid abuse even though they had been used in professional sports for over 30 years before 1961.
Tom House said that steroids were “rampant” throughout bullpens in the 1970s and that he even used HgH on occassion. He didn’t see the problem with it and even suggested steroids to some of his pitchers once he became a pitching coach.
Nolan Ryan was declining in velocity during his last years in Houston. Then, in the late 80s he goes to Texas, someone is able to reclaim his declining fastball despite surpassing 40. He was outstanding for the Rangers even claiming two more no-hitters. Who was his pitching coach? It was Tom House, who was so instrumental in the rebirth that Ryan thanked him for restarting his career during his Hall of Fame speech.
Even Hank Aaron in his autobiography claims that there was one season that he literally wouldn’t have made it through without greenies (amphetamines). That might not be a steroid, but if it enables you to finish a season that you wouldn’t have been able to finish otherwise, then it’s definitely a performance enhancer.
Anyways…I think you get the point.
